Medicare B premiums for spouse cannot be entered in TTax for 2023

Both my wife and I started taking Medicare Part B in 2023, with each of our premiums starting to be withheld in 2023. We file jointly.  I could enter my total annual amount for Part B in the TTax section for entering SSA-1099  data without a problem. However my wife's adjacent box  has a hard wired $0, and cannot be changed.  Why?  Is this entered elsewhere in TTax, or can spouse's Part B witholding amount not be used anywhere in our return??
